Assessing Dimensions of Pathological Narcissism: Psychometric Properties of the Short Form of the Five-Factor Narcissism Inventory in a Sample of Italian University Students.

To evaluate the psychometric properties of the Italian translation of the Five-Factor Narcissism Inventory-Short Form (FFNI-SF), 1,063 Italian university students were administered the scale, along with the Pathological Narcissism Inventory (PNI) and the Measure of Disordered Personality Functioning (MDPF). In general, the FFNI-SF scales showed good internal consistency (median α = .76; median interitem r = .44) and structural analyses suggested a 3-component model of FFNI-SF scales that was similar to that reported by Sherman et al. (2015). FFNI-SF second-order scales yielded meaningful convergent and discriminant correlations with PNI second-order grandiose and vulnerable dimensions. Finally, FFNI-SF second-order scales correlated in expected ways with 2 dimensions of personality dysfunction.
